People even now don't seem to think of us left handers. I took a very basic (largely to something to do/show I could still do something) course fairly recently. I'm fairly adaptable (and can use a mouse either way and my attempts at instrument playing are RH) but for the test at the end they placed me who's natural orientation with a paper is to the left of the kb and monitor, the wrong side of someone who's natural orientation with a paper would have been to the right. I complained and they swapped our seating.
